This article reviews theoretical and experimental work on the novel physics in multiband
superconductors. Multiband superconductors are characterized by multiple superconducting …

The properties of nanoscopic superconducting structures fabricated with a scanning
tunnelling microscope are reviewed, with emphasis on the effects of high magnetic fields …

Controlled trapping and guided motion of vortices via special arrangements of microholes,
so-called antidots, in YBa 2 Cu 3 O 7 films and devices is demonstrated. Resistive Hall-type …

Vortex configurations in superconducting films with regular arrays of antidots (holes) are
calculated within the nonlinear Ginzburg-Landau theory. In addition to the well-established …

Novel vortex structures are found when a thin superconducting (SC) film is covered with a
lattice of out-of-plane magnetized magnetic dots (MDs). The stray magnetic field of the dots …

We study magnetic flux interacting with arrays of pinning sites (APSs) placed on vertices of
hyperbolic tessellations (HTs). We show that, due to the gradient in the density of pinning …

Stable vortex states are studied in large superconducting thin disks (for numerical purposes
we considered disks with radius R= 50 ξ). Configurations containing more than 700 vortices …

We show, by means of numerical and analytical methods, that media with a repulsive
nonlinearity which grows from the center to the periphery support a remarkable variety of …

The vortex-vortex interaction potential in bulk superconductors is calculated within the
Ginzburg-Landau (GL) theory and is obtained from a numerical solution of a set of two …

The structure and energy of saddle point (SP) states in a two-dimensional (2D)
superconducting film of finite width w with transport current I are found in the framework of …
